C++11: std::vector vs Array

What are the main differences between std::vector and arrays in C++11?

The main differences include dynamic sizing, memory management, and ease of use. std::vector can resize dynamically, while arrays have a fixed size.

Can you explain how memory management differs between the two?

Sure! std::vector manages memory automatically, handling allocation and deallocation. Arrays require manual management, which can lead to memory leaks if not handled properly.

Which one is more efficient in terms of performance?

Arrays can be slightly more efficient due to lower overhead, but std::vector offers more flexibility and safety, which often outweighs the performance cost.

When should I prefer using std::vector over arrays?

You should prefer std::vector when you need dynamic sizing, easier memory management, or when using STL algorithms.
